To all whom i2- may concern:

' Be it known that we, HooN ARTHUR MA TEAR,'THoMAs FRANK KENNEY, and HENRY WOODI-IQUSE, subjects of the King of Eng 5 land, relsid ing at Orleans House, Edmund street, Liverpool, in the county of Lancaster, "England, have invented newand useful iniprofements in or connected with the Re cording and Indicating of the Working of Hydraulic and Electric Lifts or Hoists, of

which thetollowing is a specification. This invention has reference to lifts or hoists, primarily electrically operated lifts or hoists, and has reterence more particu- "larly to means for recording the movements of the lift or hoist; and it has for one of -its objects to provide mechanism or apparatus for recording how the lift is operated, that to say, whether it is carefully or care: lessly operated by the attendant, or Whether the lift is brought to a standstill by the attendant at its proper position by one actuation of the lift stopping and starting n1echelitism," or whether the attendant has to zelmake several attempts before the lift is brought to its proper position, that is, with the floor of the lift level with the floor of the building to which the lift may be raised or lowered. v I 7;. i so For-recording the-movements of the lift, there is-connected with the operatin or sviitch handleerecording sheet or the dike, su'chfor instance, as a paper strip working, over a drum, or a pair of drums with a length of paper passing from one to the other; audio connection wit-hit a marker or stylus is used ;-.and these are so operated bythe lift in itsmotion, and by the switch in its action-directly or indirectly-that a 40 record of the working is effected. For instance, one of such. drums may be adapted to be partially rotated so as to cause the length of paper to move forward by means of the switch mechanism when operated.-

This movement may be vimparted to the drum or driitnsby means of ratchet or other mechanism, and adapted to gear with a part of the switch, or a part connected therewith. In this arrangement," over the face of the co p'aperor drum is arranged a recording peaoil or stylus, which is adapted to move trans versely of the length of paper as the lift travels "up or down, the movement of the recording device being in onefldirection when the lift is traveling up, and in the opposite direction when the lift is traveling down.

The invention is further described with the aid of the accompanying drawin s, which illustrate an electrically operatedliit with a recording apparatus having the to characteristics as above described, but while this particular form of apparatnsisron venient and advantageous, the invention is not restricted to it, but under varying coii ditions of use, may be modified and arranged difierently to suit such varying conditions; and While it is shown as applied to an electrically operated lift or hoist, it is to be understood that with suitable modificw tions, it may he applied to lifts operated hydraulically, or otherwise M In the drawings, Figure l, is a diagrammatic View showing the apparatus and the upper part of the electric lift inachiner Fig. 2 is a front'elevation, andlligi 8 an end 1 t1" elevation of the recording; apparatus proper; and Fig. i is a cross section show ing a slight modification of the app'aratusQ- Fig. 5 is a view of part of Fig. Zillustratingm, v an automatic clutch mechanism between a .80 driving sprocket wheel and a screw whicl serves to move the recording marker; and Fig. 6 illustrates a part of a record obtained from such apparatus.

' Referring now to thedrawings, a represents the electric motor, and E5 the pulley, over which the lift cage ropes-which are, indicated by the dot-ted lines c-pass; and d is the pulley shaft. in the case shown, the motion of the lift cage is transmitted to the recording instrnment -the construction of which is shown in Figs. 1 to l-from'the shaft a3 through'a sprocket chain c, or other driving gear, which passes over and revolves a Wheel f on the threaded shaft j; and this operates the marker g to and fro in the manner hereinafter ox lained. The aper which is to be marks upon by themes er 5/, is moved forward the re aired amount at each actuation of the switkc es of themotor, through acord or chein connection 1: which may be directly connected to the plunger or core 2' of the solenoid connected with and operating the hrakes oi the machinery, the solenoid being energizied and deenergized with the switch is operated in stopping and starting the lift. Or, the means for operating the er tceding device may switch r more C(JUYQIHL'LM or detransmitted to the the marker 7 is operated by the lift ca e or chamber raislug and. lowering part or the .urt machinery, While the paper moving echanisin is oper ted, indirectly, through 1e movement of the switch mecl'ianisui of machinery; but the invention is not zed to this particular manner of opernce, the marker might be I by the switch mechanism directly or .lirectiy, an i the paper now ed by the raisnd lowering p t of the machiner ng now more particularly to the rs-l 3, showing the apin detail, on the threaded spindle f provided a nut is having connected fitting it" which slides on the bars pports on hinge the carrier 9 .1. e marker 7 ed; and as the revolved in one direction or the 'imn the raising and lowering part nacliineiy of the lit, the marker g moved bac 1 forward in lzvva c. the apparatus transversely. The paper I is stored on SM p--nu sh is designated I) ads onto Winding on the roller 0, which wpted to be moved a. certain amount 0 switch is operated through this movement b effected by upon the lever, and a ratchet on the spindle 0 of the shaft of partial revolution action, and so moves the paper Z under pencil 0 marker a. short distance each. time the switch is operated. The. pawl j is normally ed toward the ramhet Wheel 0 by a spring j and the marker carrying arm 9 pressed toward the table 72 by a U The shaft 0 of the. roller 0 has i i amped brake p connected With it, operating in connection with a stop 3), so that the rotation of the roller 0 is braked and steadied when being actuated. In the apps ratus shown in rigs. 2 and 3, the roller 0 supported by conical pivot pins at each end. the ends of which fit into conical sockets in the shaft 0; and one these pivots an operating handle Q for easily screwing it up and nose: Wing it, so that the er 0 can be readily taken out when full, z. a fresh sheet fastened to it when re quired. In the operation of this annngea length. of paper Z to be moved meat of the apparatus, the actuation of the tiou ivill cause the rerun-ding marker 9 or device to make a mark (Fig. ll) on the recording sheet or paper 5 lengtlnvisc; and when the svvitch is moved so as lo start the lift in one direction or the other, the recording device 9 will be caused, through the threaded shaft f and nut it, to travel trans versely of the apparatus and shaft, and mark a transverse line 7 on. the paper. In bringing the lift or hoist to a standstill. at any certain floor or level, if the attendant is careless in eli'ecting this, or the lift or hoist is caused to travel either too far, or not far enough, and this requires a further operation of the stopping and starting switch, or if the attendant is not proficient in the operation of the lift or hoist, these twoor three attempts at bringing the lift to its proper position, and any other sudden or improper working of the lift or hoist, will be recorded and exhibited by means of short lengths of vertical and horizontal lines as indicated at in Fig. 6; Whereas, if the lift or hoist has been operated and brought to-its proper position at a single operation, there simply one short length of line y in the longitudinal direction of travel of the paper at each point of stoppage; and the absence of other markings will show the lift or hoist to have been properly and carefully Worked.

By the above means, the proficiency of the attendantis exhibited and recorded; and

this will cause him to take greater care in the Work of operating the lift or hoist, as not only is such careless operation inconvenient to persons carried by an electric lift, but it also ,nieans, waste of power in operatiz ig electric lifts or hoists, and is very liable to cause damage and serious expense. The above n-ieans also provide a record of how inany'tinies the lift has been in use,

and the loors of the building to Which the lift is operated, and is a general index and record of its action.

fastened in this position by the hooks s.'

In such a case,'the sto l'ing roller m may be adapted to hold a large quantity or store of paper; and when a certain amount is wound on the roller 0, say for a given time, the sheet can be torn and cut, and the record removed from it, and then the fresh edge of the paper fastened and secured to the roller 0 as described, and the machine can then go on recording. This can be repeated In the modification shown in Fig. 4, the

the effect of disarranging the concurrent action or movement of the driving wheels and the marker, and to counteract this.

there may he provided on the spindle f aclutch or equivalent slip device a which serves to engage the wheel f, with a collar o mounted on the spindle, and adapted to re volve therewith. The wheel f is free to slide longitudinally on the spindle f being held in engagement with the collar c by a, spring f and to be revolved therewith under normal conditions, but should any resistance to the revolution of the shaft take place, due say to the marker carrier reachingthe end of its predetermined stroke, the sprocket wheel f will he disengaged from the collar 2) and Will then revolve freely on the shaft, and so danger of the marker coming olf the paper, or the apparatus becoming deranged, is avoided.
